Electroplating

Electroplating is the process of using an electrical direct current to coat an electrically conductive object with a thin layer of metal. EPi offers a variety of high-quality electroplating processes that are ideal for all types of metal finishers. Learn More

Cleaners

All metals need to be cleaned prior to electroplating, blackening, or finishing. Metalworking fluids and carbonaceous smut need to be removed in a soak, spray, electroclean, or ultrasonic cleaning. A properly cleaned part will have excellent adhesion and be brighter, blacker, and smut-free. Learn More

Acid Salts

Dry-powdered and liquid acid salts are specifically formulated for removing rust, scale oxides, stains, and smut from a variety of metal surfaces. Acid salts are also used to activate metal surfaces for further finishing. Learn More

E-Kleen 154 is a liquid concentrate blend of acid, solvent, surfactants and complexers, formulated to achieve in one step, the cleaning and preparation of a variety of metal surfaces prior to blackening, phosphating and chromating. It is recommended for use following conventional alkaline soak cleaners to ensure neutralization of residual alkalinity prior to acidic blackening or oxidizing processes. It is an effective surface conditioner/activator prior to Insta-Blak acidic blackening processes. It will remove light oils, light rust, light heat-treat scale and most shop soils efficiently and quickly.This metal cleaner can be bought online.

It is a general purpose metal activator and deoxidizer containing fluoride which is used at room temperature on steel, copper, brass, and zinc.

E-Pik 215 is a free flowing mixture of dry acids and is more convenient and safer to use than liquid mineral aids. It does not produce the undesirable fumes given off with strong acids. It is dissolved in water and used at ambient temperatures to remove light to medium surface rust from steel and to activate steel surfaces prior to blackening with EPI's Insta-Blak or Ultra-Blaksolutions. Heavily rusted surfaces may require elevated temperatures of 150°-170° F. No venting required when used at ambient temperatures. It is used following the water rinse after cleaning the steel surfaces with EPI's E-Kleen alkaline soak and electrocleaners.

E-Pik 215 is more moderate in its action on steel surfaces than mineral acids and produces a uniformly active surface. It is also used to activate zinc plated surfaces, die-cast zinc surfaces and copper and copper alloy surfaces prior to blackening, oxidizing, antiquing, plating, chromating, or other finishing.
